Use the method of completing the square to transform the quadratic equation into the equation form (x + p)2 = q. 1 + 2x + 2x2 = 0 a) (x + 0.5)2 = 0.5 b) (x + 0.5)2 = -0.5 c) (x + 0.5)2 = 0.25 d) (x + 0.5)2 = -0.25

The physical fitness of an athlete is often measured by how much oxygen the athlete takes in (which is recorded in milliliters per kilogram, ml/kg). the mean maximum oxygen uptake for elite athletes has been found to be 60 with a standard deviation of 7.2. assume that the distribution is approximately normal.

[10 points, algebra 2-simplifying complex fractions]according to my answer key the restrictions are -1 and 4. but why not positive 1?

Give me the equations of two lines that have the same slope but are not parallel.
